MANUAL AIR CONDITIONER SYSTEM
TEMPERATURE CONTROL DIAL (TEMPERATURE CONTROL)
Increases or decreases the set temperature.
RECIRCULATION (
) SWITCH
• When REC switch is ON, REC switch indicator turns ON, and air inlet is set to REC.
• When REC switch is turned OFF, or when compressor is turned from ON to OFF, REC switch is automati-
cally turned OFF. REC mode can be re-entered by pressing REC switch again.
• REC switch is not operated when DEF switch is turned ON, or at the D/F or FOOT position.
REAR WINDOW DEFOGGER SWITCH (IF EQUIPPED)
When switch is ON, rear window is defogged.
OFF SWITCH (BLOWER SPEED SET TO 0)
The compressor and blower are OFF.
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch will turn off the A/C switch and compressor.)
MODE DIAL
Controls the air discharge outlets.
FRONT BLOWER CONTROL DIAL
Manually controls the four blower speeds.
MAGNET CLUTCH CONTROL
When the A/C switch is pressed, or the mode dial is turned to the DEF or D/F position, the front air control out-
puts a compressor ON signal to BCM.
The BCM then sends a compressor ON signal to ECM, via CAN communication line.
ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant pressure sen-
sor signal, throttle angle sensor, etc.). If it judges compressor can be turned ON, it sends compressor ON sig-
nal to IPDM E/R, via CAN communication line.
Upon receipt of compressor ON signal from ECM, IPDM E/R turns air conditioner relay ON to operate com-
pressor.
